HOOD FOR EMERY-WHEELS.

I To all whom it may concern:

Be it known that I, GnonenW. Funnow, a citizen of the United States,residing at Troy,-in the county of Miami and State of Ohio, haveinvented certain new and useful Improvements in Hoods for Emery-Wheels,of which the following is a specification.

My invention relates to improvements in hoods for grinding, polishingand buiiing wheels.

The object of my invention is to provide a hood which will beparticularly effective in carrying away the dirt and dust incident todevices of this character, the invention being more particularly adaptedfor removing dust from above the work and also those particles whichadhere to and are carried around by the wheel and are thrown ofi atapoint where the work is applied.

Theinvention consists in the constructions and combinations of partshereinafter described and set forth in the claims.

In the drawings: Figure 1 is a side elevation of the device embodying myinvention. Fig. 2 is a vertical section on the line ww of Fig. 3. Fig. 3a front view of the same. Fig. 4t is a top plan view of the hingedforward portion of the conduit hereinafter referred to. Fig. 5 is asection of the same on the line y-y of Fig. d.

Like parts are represented by similar charactors of reference in theseveral views.

In the said drawings, a and (1 represent the hood of my improved device,preferably formed in two parts hinged together at a in the usual manner.

a represents a grinding, polishing or buding wheel mounted upon one endof the shaft 0; which is supported in suitable bearings on the'standarda The hood or casing extends about the wheel except for the open portionat the forward end and has attached at its rear end a conduit a whichmay be connected to any suitable form of suction fan in the usual Way.

Located in the upper and rear portions of the hood is a division wall 6which extends from side to side of the hood so as to form a conduit 6which communicates with the conduit a the conduit 72 beginning at theforward part of the hood immediately above the work and being adapted toreceive the dust and dirt, which will be carried rearwardly through thesame into the main conduit a.

It has been common in devices of this kind Specification of LettersPatent.

Application filed February 21, 1910. Serial No. 545,079.

Patented as a, rare.

to leave an open space between the wheel 4 i and the upper part of thehood and it has. I

by the current of air created by the revolution of the wheel.

To compensate for the wear on the wheel and also for difierent sizedwheels, I have the forward part of the division wall, 6, in the natureof a hinged portion, 0, pivotally supported at c to the forward part ofthe division wall proper. A thumb-screw extends througl'i the slottedopening 0 in a side of the hood and engaging an ear or lug 0 on thehinged portion, furnishes the means for holding this hinged portion inany. position of adjustment with respect'to the wheel. I also slidinglymount in suitable guides (Z on said hinged portion a sliding shield 03,which may be held in any position of adjustment with respect to saidhinged portion 0 by the said screw (i This shield, (Z, may be slid downto any position desired with respect to the wheel and prevent the smallparticles which adhere to the wheel from flylng up into the face oftheoperator.

Having thus described my invention, I claim:

1. In a device of the character described, a wheel, a hood, forsaid-wheel formed with a work opening at the forward portion thereof,and a conduit 'in' said hood closed to the wheel and extending upwardlyover said wheel, substantially as specified.

2. In a device of the character described,

a wheel, a hood for said wheel formed with I a work opening at itsforward portion, and a conduit in said hood closed to the wheel andextending upwardly over said wheel,

said conduit beginning at a point coincident with said work opening,substantially as 3. In a device of the character described,

' a wheel, a hood for said wheel formed with thereof, a'conduit in saidhood closed to the Wheel and extending upwar 1y oveI-szt'id Wheel, andan adjustable hinged portion at the forward end of said conduit,substan' 5 tially as specified.

4. In a device of the character described, a Wheel, a hood for saidWheel, and a conduit formed in said hood' extending upwardly over saidWheel, saidconduit hav- 10 ing an adjustable hillgdTOllllOIl at the for-Ward end if reef, and an adjustable shield carried by s m. hingedportion, substantially as specified.

In testimony whereof, I have hereunto set my hand this 10th day ofFebruary, 1910.
